Seeker,

Yes, I think so. By so doing God may have intended to also illustrate the fact that He gives every one of us the opportunity to repent and accept His provision for our salvation right up until our last day of life.
You wrote: Besides, that would mean Noah was keeping the wicked from heading for higher ground too. Nasty trick.
The wicked had no time to head for higher ground. The Bible seems to say that the flood was primarily caused by "waters from the great deep" which "burst forth." I believe this probably refers to tidal waves which came from the Persian Gulf. I believe the land of Noah was far enough inland from the Gulf that it escaped the crashing force of those tidal waves but was, nonetheless, quickly and completely flooded with water, allowing no time for those outside the ark to move to higher ground.
You wrote: The seaworthiness of all wooden ships is clearly not in question.
Read Jan's article attempting to debunk the possibility that Genesis is describing a large local flood. You will see that is indeed part of what he is questioning.
You wrote: It is the particular design of the ark that was so stupid. If God designed it, He made a shape guaranteed to fail.
That is odd. I have always heard that the ark's 6 to 1 length to width size ratio is the perfect ratio for large seagoing vessels, and creates a vessel that is very stable and cannot be easily capsized. I have also heard that that this proportion of length to width continues to be used by navel architects.
You wrote: If the flood was as cataclysmic as flood believers are forced to say it was (to make the mountains, freeze the arctic, destroy civilizations), the ark would have been in for a heck of a ride. ... The ark would have been in splinters in no time flat.
You seem to forget that I do not believe Noah's flood covered the mountains and froze the arctic. I believe Noah's flood was a large inland flood which covered only the land of Noah, a "land" which may have been only 30 or 40 miles across.
